Abstract

PCT No. PCT/IL96/00105 Sec. 371 Date May 28, 1998 Sec. 102(e) Date May 28, 1998 PCT Filed Sep. 9, 1996 PCT Pub. No. WO97/11047 PCT Pub. Date Mar. 27, 1997A cation exchange membrane mediated acid-salt metathetic process. An aqueous salt solution is placed into a first compartment on one side of the membrane together with an organic amine extractant of limited water miscibility, and an aqueous acid solution is placed into a second compartment on the other side of the membrane. Product acid forms in the first compartment and collects in the organic amine extractant from where it is recovered. The process is particularly suitable for the recovery of a carboxylic acid from its salt.
